ASPINNING-FRAME.

SPECIFICATION forming part of Letters Patent No. 621,531, dated March 21, 1899.

To @ZZ whom it may concern,.- i

Be it known that we, CHARLES MARIINOT and AIME GALLAND, engineers, citizens of Germany, residing at Bitschweiler, Alsace, Germany, have invented certain new and useful Improvements in Spinning-Frames, (patented in Great Britain VDecember 16, 1896, No.' 28,811; in France October 5, 1896, No. 260,209; in Germany October 14, 1896, No. 92,604, and in Switzerland January 2, 1897, No. 13,600,) of which the following is a specification.

This invention relates to continuous-spinning frames; and its object is to prevent the piling up of the threads which are being wound upon the cop-tube during the period that the ring-rail or thread-guide is reversing its motion.

The invention consists of la construction whereby the spindle carrying the cop-tube is given a reciprocating movement during the interval that the ring-rail or thread-guide is stationary at the end of its stroke. y This motion of the spindle causes the thread to be crossed upon the cop instead of permitting it to wind anumber of turns in the same plane.

The invention will be described with reference to the accompanying drawings, in

, which- Figure 1 represents one of the spindles in the position occupied by it during the chief part of the winding with the adjacent parts in section. Fig. 2 is a View of the same apparatus, the spindle being represented at the end of its reciprocating movement in one direction.

Referring to the drawings by letter,.A represents the spindle, mounted in the frame A in such a manner as to freelyA movetherein in a longitudinal direction. The lower end of the spindle is provided with an offset finger o, which rests upon the periphery of the cam C, havinga V-shaped notch c. The cam is carried by a shaft P. The spindle is surrounded by a coiled spring ct', tending to hold the linger a against the periphery of the cam or to elevate the spindle. The cop O is carried at the upper end of the spindle. l

B represents the ring-rail, carrying the ring b, through which the cop is adapted to pass when the rail makes its usual up-and-down motion to guide the thread. This upanddown motion of the rail may be imparted through the bar B in any suitable manner.

The operation is as follows: When the rin g rail arrives almost at the end of its upward travel,the cam presents its notch to the finger a and permits spring a to suddenly elevate the spindle and cop to the position shown in Fig. 2, the spindle moving in a straight line concentric with the ring b. Immediately the spindle has' reached the end of its upward stroke it is returned to its original position by the cam, the sudden inclination of .the notch c accomplishing this. This reciprocat ing movement of the spindle is eifected while the ring-rail is reversing the direction of its movement and is practically stationary, and it causes the winding to cross upon the mean diameter of the cop, as shown in Fig. 2, instead of winding several turns at one point. The reciprocating movement of the spindle is repeated at each stroke of the rin grail.

Although the invention has been described only with reference to machinery in which the ring-rail and the spindles move in vertical lines, it will be understood that it is equally applicable to other continuous-spinning machinery in which the spindles may be arranged at an angle or even horizontal.

Having described our invention,'we claim- In continuous-spinning machinery, the combination with a reciprocating ring-rail of a spindleand'means for impartinga forwardand-return motion to the spindle during the periods in which the ring-rail is reversing its movement, substantially as described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 25th day of March, 1897. p
